• Move the write-protect switch to the right to disable write protection
(existing data on the tape can be overwritten, and/or additional data can be
appended to the media unless the cartridge is write-protected via software).
When write-protect is disabled, no orange rectangle is visible.
When a tape cartridge is loaded in the drive and the tape cartridge’s write-protect
switch is moved to its write-protected position (to the left as you face the label/
switch side of the tape cartridge), the drive turns on its write-protect indicator
immediately. If the drive is currently writing to the tape, the write-protect feature
does not take effect until after the current WRITE operation completes.
